No.
A-9594 HIGH-VOLTAGE, HIGH-CURRENT DARLINGTON ARRAY Integrating seven high-voltage, high-current npn Darlingtons into a monolithic power array, the ULN7003A AND ULN7003LW are designed for interfacing between TTL or CMOS logic and a variety of peripheral loads.
The seven open-collector Darlington outputs are specified for 135 V minimum breakdown and 90 V minimum sustaining.
Included are integral power diodes for switching inductive loads.
Typical applications include relays, lamps, print heads and hammers, solenoids, and level shifting to power discretes.
The ULN7003A/LW include input current-limiting resistors compatible with the drive capabilities of TTL and (most) CMOS operating at a nominal logic supply of 5 V.
Operation with 12 V CMOS may require additional input current limiting.
The high sustaining voltage rating of this power array makes it ideal for inductive load applications where Zener diode flyback techniques are used.
The increased flyback voltage provides a much faster inductive load turn-off current decay that is especially useful with dc stepper motors, solenoids, and print heads.

10A Note the ULN7003A (DIP) and the ULN7003LW (SOIC) are electrically identical and share a common terminal number assignment.
